METAL WINDOW-FRAME.

Specification of Letters Patent.

Patented Apr. 19, 1921.

Application filed July 1, 1919. Serial No. 307,945.

T 0 all to loom it may concern Be it known that I, IRVING H. ELLIOTT, acitizen of the United States, residing at New York, in the county of NewYork and State of New York, have invented a certain new and usefulImprovement in Metal Window-Frames, of which the following is aspecification.

The invention relates to metal windowframes of the type set forth in U.S. Letters Patent No. 1,237,295 to Harry E. Campbell, dated August 21,1917, wherein are comprised hollow jambs having their inner wall formedof three vertical sections, separated by slots. The invention consistsin an 1 m provement of said jambs, whereby a portion of either of saidslots may be varied in width without disturbing the remainder of theslot; whereby the width of said slots may be initially adjusted, andwhereby the construction of the jamb and especially of the inner wallthereof is simplified, cheapened and involves the use of less metal.

In the accompanying drawings Figure 1 is a vertical section of mywindow-frame. Fig. 2 is an elevation of a portion of said frame withparts broken away to show the supporting brackets for the inner jambwall section D. Fig. 3 is a horizontal section on the line 3, 3 of Fig.4. Fig. 4 is a vertical section, similar to Fig. 1, showing the sashesI, J in place in the frame. Fig. 5 is a vertical section on the line 5,5 of Fig. 3.

Similar letters and numerals of reference indicate like parts.

The frame comprises the lintel A, the sill B and two hollow jambs C,alike in construction, one of which only is here shown.

The sill B, which is a casting resting upon the masonry of the windowopening, has a flat portion 1 united to an outwardly and downwardlyinclined portion 2 by a vertical portion 4. Near the outer edge of theflat portion 1 is a groove 6. The top surface of the rib 7 formedbetween the groove 6 and the vertical portion 4 lies below the level ofthe flat portion 1, so that any water accumulating on said flat portion1 andv entering the groove 6 will flow over said rib 7 and so escape tothe vertical and outwardly inclined portions of the sill. In this way,said sill is drained and water prevented from flowing into the buildingover the rear edge of said flat surface. 7

The top wall 8, the rear wall 9 and the upper part of the front wall 10of the lintel A. are lntegrally formed of a bent metal plate. The lowerpart of wall 10 and a portion of the bottom wall of the lintel is formedof a bent plate 11. The upper portion of plate 11 is united in anysuitable way, as by welding, to wall 10. The rear edge of the horizontalportion of bent plate 11 1s flanged upwardly and is inwardly inchncd, asshown at 12. The remainder of the bottom wall of the lintel is formed ofa plate 18 having its outer edge flanged upwardly and inwardly to faceflange 12, as shown at 14. The inner edge of plate 13 is bent over toform a horiaontal loop 15 which engages with a similar horizontal loop16 on the lower edge of rear wall9. The ends of the lintel are closed.In the lintel bottom are openings which are covered by internal plates,one of which is shown at 17, secured in place by screws 18. The flanges12, 14 extend upwardly between said plates into the lintel. Integralwith each of said internal plates is a downwardly projecting bar 19,Fig. 2. Directly beneath said bar and secured to the sill is a bracket20. A plate D is attached to the outer faces of bar 19 and bracket 20 bymeans of screws 21 passing through horizontal slots. Said plate, as willhereafter more fully be explained, forms one of the three sections whichtogether form the inner wall of the jamb.

The two hollow jambs being, as heretofore stated, exactly alike, Iproceed to describe the one shown in the drawings. (See Fig. 3.) Aportion 24 of the front wall, the outer wall 25 and the rear wall 26 areformed integrally of a bent metal plate. 911 the vertical edge of wall26 is formed a loop 27 which engages with a similar loop 28 on thevertical edge of section D. 29 is a vertical channel plate, one arm ofwhich is in line with section D and forms another section E of the innerwall of the jamb. The opposite and parallel arm 30 is united to the bentover end 31 of front wall 24, so that the portion 32 of said channelplate 29 which connects section E and arm 30 completes the front wall ofthe jamlo. The arm 30 is wider than section E, so that between sectionsE and D there is a space, in which are disposed two narrow verticalplates F and G placed one above 7 vertical face 4 of the sill. 65

the other, but separated at their abutting ends, as indicated at 33,Figs. 4 and 5. The top edge of plate F bears against the bottom oflintel A. The bottom edge of plate G rests upon the flat upper surfaceof a shoulder 34 formed at one end of the inclined portion 2 of the sillB. The width of these plates F and Gr is the same, and is less than thatof the space before referred to as existing between the facing edges ofsec tions E and D, so that two narrow slots 35, 36 are produced adjacentto said vertical plates F and G.

To the arm of channel plate 29 are bolted four brackets, one of which isshown at H, Fig. 3. The upper plate F is connected to the upper two ofthese brackets by screws 37, 33 passing through horizontal slots in saidplate. In like manner, the lower plate G is connected to the lower twoof these brackets by screws 39, 40, also passing through horizontalslots in said plate. The two plates F and G thus sup ported registerwith sections D and E, so that it will now be seen that the whole innerwall of the jamb consists of three sections, namely, D, E and theintermediate plates F and G disposed one above the other, between whichsections, as I have stated, are the two parallel vertical slots 35 and36, extending from top to bottom of the wall.

This construction of the inner wall of the 'jamb simplifies and cheapensthe manufacture of jambs of this general type, wherein the inner wall ismade of three vertical sections. Ordinarily the two outer sections ofthe three are secured to or form parts of the front and rear walls ofthe jamb and the middle section is supported by a Vertical plateextending across the interior of the jamb and secured to the oppositewall, such construction, for example, being shown in U. S. LettersPatent to Harry E. Campbell before noted. By the introduction of thechannel plate 29 and the securing of the two plates F, G of the middlesection directly to the brackets H carried on said channel plate, Iobtain a shorter and more rigid support for this section of the innerwall, and at the same time eliminate the long plate which in the deviceof he aforesaid patent crosses the interior of the jamb and supports themiddle section.

In order more clearly to explain the further advantages of my presentwindowframe, I have shown in Figs. 3, 4 and 5 vertically sliding sashesdisposed in the frame, the construction of said sashes, however, notbeing herein claimed. I is the upper sash and J the lower sash. Thelower member of sash J has a vertical downwardly projecting plate 41which, when said sash is closed, as shown in Fig. 4, bears against theOn the rear side of said member is a plate 42 inwardly bent theremainder comparatively loose.

and then turned downward, so that (also when said sash is closed) saiddown turned portion enters groove 6 in the sill. Hitherto where thelower sash has been constructed, as described, to cooperate with a ribon the sill received between plates like 41 and 42, said rib projectsabove the level of the flat portion 1 of the sill, and so forms a dampreventing the escape of water lodging on said flat portion. But byplacing the rib below the level of the fiat surface 1 of the sill, it isobvious that this dam is eliminated, and that there is always freedrainage of the water over the rib and so to the outer inclined sillsurface 2.

The upper sash I has an upwardly projecting plate 43 which entersbetweenthe upturned flanges 12, 14 of plates 11, 13, and on the sides ofthe sashes are plates 44, 45 which are received respectively in theslots 36 and 35. For the sake of clearness, I have omitted thesuspension devices and counterweights for the sashes.

Returning to the inner wall of the jamb, and particularly to the platesF, of the middle section thereof. it is to be noted that by reason ofthe horizontal slots in them, through which the a taching screws 37, 38,39, pass, each of these plates can be adjusted laterally by looseningthe screws and sliding the plate in one direction or the other. Thisenables me to make one part of either slot 35 or 36 tight, while leavingFor example, with the sashes closed, as shown in Fig. 4. 1 may move theupper plate F to the right of the drawing, so more closely engaging theside plates 44 of the'upper sash I in the upper part of their slot 36,and I may move the lower plate G to the left of the drawing, so in likemanner clamping the side plates 45 of the lower sash J in the lower partof their slot 35. But this movement of the two plates correspond inglyincreases the width so much of slot 36 as is below the upper sash, andso much of slot 35 as is above the lower sash. Consequently as eithersash is moved to open the window, its side plates run more and more intothe widened portions ofthe slots and hence travel freely therein, sothat although when closed the sashes are closely engaged, they are,nevertheless, easily opened.

In Figs. 4 and 5, I have shown packing blocks 46 which, when the sashesare closed,

bear against the ends of the meeting rails 47, 48. These blocks arebolted to the upper plates F of the middle section and their free lowerends extend over the joint 33 between said plates and the lower platesG, so that their presence offers no obstacle to the independent lateraladjustment of the said plates, as above described.

In order to adjust the initial width of, the

slots 35, 36, the screws which secure the brackets H to the plates F andG pass through slots in said plates, and the screws 21 which attachsection D to the brackets 20 and bar 19 also pass through slots in saidsection, so that by loosening these screws, said sections may besuitably moved with respect to one another, and the plates of the middlesection with respect to section E. The loops 2'7, 28 are given sumoientplay within one another to permit of this movement of section D. Theloops l5, l6 connecting the lintel plates 9 and 13 are also givensuflicient play within one another to enable the flanges 12, 14 onlintel plates 11 and 1.3 to be adjusted with respect to one another soas more or less tightly to engage sash plate 43.

I claim:

1. A metal window-frame, comprising a hollow jamb having its inner wallformed in three sections with vertical slots between them, the middlesection being formed of two separated plates disposed vertically oneabove the other and laterally adjustable each independently of theother.

2. A metal window-frame, comprising a hollow jamb, comprising a bentvertical plate integrally forming the rear wall, outer wall and aportion of the front wall of said jamb, a channel plate having one armunited to said first-mentioned plate, the other arm forming a verticalsection of the inner wall of said jamb, and the portion of said channelplate between said arms completing the front wall of said jamb, avertical section of said inner wall united to said rear wall, supportsfor said section, brackets on channel plate arm, and a. middle verticalsection of said inner wall interposed between said sections and carriedby said brackets; there being vertical slots between said sections.

3. A metal window-frame, as in claim 2, the said middle section beingformed of two plates disposed one above the other and independentlyadjustable laterally upon said brackets.

4. A metal window-frame, as in claim 2, the said vertical section beingunited to said rear wall by mutually engaging loops and laterallyadjustable upon said supports.

5. A metal window-frame, comprising a hollow jamb having its inner wallformed in three vertical sections with vertical slots between them, themiddle section being formed of two separated plates disposed one abovethe other, supports for said plates, the said plates being laterally andindependently adjutable upon said supports, and a packing block 45secured upon one of said plates and having its free end overlapping thejoint between said plates.

In testimony whereof I have afiixed my signature in presence of twowitnesses.
